hostname: fix conflicting installs of /bin/hostname

Surprisingly long-standing issue with conflicting /bin/hostname
installs.  Reported as early as November 2005 by Joseph Dupre.

All together at one point or another there are at least 4 possible
sources of /bin/hostname:

        busybox
        util-linux
        coreutils
        net-tools

Buildroot depends on the -F flag being available in the default
/etc/inittab.  Out of the 4 listed projects only net-tools and buildroot
for sure support the -F flag.  I'm a little unclear on util-linux as it
has been removed entirely (in favor of net-tools) for some time.

As of coreutils 6.9.90 (2007-12-01), coreutils does not install its
/bin/hostname by default.  The following commit reenabled its build:

d6e58cb coreutils: fixed missing hostname (Sep 2010)

This was done to fix a build error in coreutils regarding help2man.  A
later patch:

30c5105 coreutils: bump to version 8.21

disabled the help2man functionality entirely but left hostname being
installed.

On a very related note, net-tools now contains an obsolete check to add
util-linux as a dependency to force it to build first (so that net-tools
ends up with /bin/hostname).

This patch fixes both of these issues so that hostname always comes from
one of two places:

    busybox
    net-tools
